Windows agent migration to new server

I'm running BE 20 for Windows and backing up my iscsi data volumes to a Dell OST deduplication device. I'm getting ready to migrate several Windows 2008 R2 servers running the BE agent to new Windows 2016 servers. Each migrated agent will keep it's host name and IP, and I want to make sure the new backups continue to be deduplicated against the previous backups.

Do I need to do anything special to prep for that? I've found docs about migrating the BE server, but not the remote agents. Here's my plan:

• Shut down the old server, bring up the new server; rename  with old server name and rejoin domain
• From BE server, establish trust relationship with new server and install agent
• Install OST dedup plugin on agent

Is there anything else I need to do to deduplication recognize the previous backups?

Thanks.
